- Application filed June '7,

This invention relates to salvage ships and has tor an object the provision o-a ship which7 vwhile especially designed for raising disabled submarine and other vessels, will be equally useful for raising and salvaging y rially increased.

Another object of the invention is the-provision of a novel form of hull which is especially adapted or raising heavy objects, as the weight of such objects may be distributed evenly throughout the hull so that the latter will remain upon an even keel under the weight of the object being raised.

Another obj ect of the invention is the provision of a hull which while possessing the requisite amount oi buoyancy and displacement for Vraising objects oif great weight, may be propelled through the water with'a minimum amount oi' power due to the shape and e character of the hull which Oilers a minimum amount of resistance :for a vessel of this type.

With the above and other objects in view, the invention further includes the 'following novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of a salvage ship constructed in accordance with the invention and illustrating the manner of raising a submarine vessel.

Figure 2 isa top view oic the ship.`

Figure Slis a bottom plan view.

Figure t is a Jfront view. A

Figure 5 is a section on the line 5-5 of Figure 2. v

Figure 6 is a rear view. v

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the hull. of the ship which is indicated at 10 is ot sufficient buoyancy and displacement to permit hoisting submarine vessels or other objects of great weight.

A1929;l seria; n. eeaiie This hull is of novel construction being bifurcated orvthe major portion of its length so as to providea central longitudinally disposedwellll andspaced longitudinally disposed pontoons y12 upon opposite sides of the well. These pontoons are connected at the bowand stern of the hull so as to provide a rigid hull structure, and as the character of the vessel requires that the hull be relatively broad, the bow of theI hull is provided with a passage 13 which communicates with the well 11. The top ot'this passage forms an archlll which is positioned above the ynormal water line of the hull, so that when'the vessel moves forward, a minimum amount of resistance will be offered. The rear end of the Y well 1'11is in communication with rearwardly and laterally Vextending passages 15 which extend through the hull, so that rwater in the passage or well *11 will be provided'with a ready outlet vthrough these passages 15.

' The ponto'ons 12 are suitablybraced as indicated at 16 and their decks 17 are `provided with longitudinally extending rtrough-lille depressionsl-S within which are secured rails 19. By reference to Figure 5'of the draw I ings it will be seen that the rails are disposed longitudinally of the pontoons upon opposite sides of the well 11 and these rails form guides for carriages 2O which are provided k80 with grooved wheels 21 to engage the rails.

Two or more of these carriages are preferably provided and the carriages extend transversely across the well 11 and support windlasses 22 or other hoisting apparatus which may be driven b-y an electric motor asindicated at 23,or by any-other suitable source of power. The windlasses operate block and' talls 24 which are adapted to be secured to the object to be raised.

v The portion of the hull abait the well 11 accommodates the boiler and engine, or other motive power of the ship. l

The ship may also'be providedwith derriclrs 25 and 26 to Jform additional hoisting apparatus, and the 'derrick 26 may support a diving bell 27 and a ladder 28 for the accommodation of divers. Y

This submarine has attached thereto a saddle 30 and attached to this saddle is a'bridle 3l which extends from an equalizing member 32 engaged with the hooks of the block and falls 24. VThe bridle in additionrto being attached tothe saddle 80 alsorextendsiaround the bowandsterniof the submarine as shown at 33 and 34 respectively, while a guard or Vlocking device 35 is provided at thebow to prevent slippage.
